How It Works

Contactless memory cards do not have batteries and have no processing power for data management. All memory cards communicate to readers through synchronous protocols using radio frequency (RF).

There are six main types of RF memory cards in common use today. Although they may look similar, they are known by the following names and characteristics. All of them are contactless - you only need to put them in proximity of the reader to be detected and the data can be read. We are able to duplicate the straight memory cards - not protected cards or stored value cards.

Ultra-High Frequency Cards - Note that we can only do low-frequency (Khz) and high-frequency (Mhz) cards at this time. We cannot duplicate ultra-high frequency (Ghz) cards, such as used for garage entry and which operate over a distance of several meters. Other companies may be able to help you duplicate these type of cards. Search for the manufacturer's representative.

Other Limitations - Please note that we cannot copy magnetic stripes such as used on hotel key cards and we do not have any capability to print on the cards. We do not cut metal keys and we do not sell blank cards. We do not keep your card data and so you cannot order a replacement unless you have an original card to duplicate.

Specialised Cards

In the 'arms race' to provide better proximity card security, there are always new innovations. We have seen some hybrid cards that incorporate two technologies. Mango dual frequency RFID is one such card.

For example, one physical card may use EM for the common areas and iClass or Mifare to access the apartment. We may be able to duplicate one or both technologies, but we can only do so by copying each feature of your original card to a separate blank card. So you will end up with two access cards.
